In the README, there is a section that takes about running cmake -LH | grep "BEMAN_INDICES_VIEW" -C 2.

I tried running that on my local machine and I got this warning:

CMake Warning:
  No source or binary directory provided.  Both will be assumed to be the
  same as the current working directory, but note that this warning will
  become a fatal error in future CMake releases.

Running cmake -LH -S . | grep "BEMAN_INDICES_VIEW" -C 2 (note the added -S . flag to the CMake command fixes the issue.

My CMake version is 4.0.2, and I am on Ubuntu 24.10.
